Intestinal neuroendocrine tumors (INETs) represent the highest percentage of this type of lesion in the digestive system. The treatment of choice is removal of the primary lesion and its regional lymph nodes. The aim of this study is to report the results of patients with INETs treated surgically, in terms of postoperative morbidity (POM) and mortality. Series of cases of patients with intestinal INETs operated consecutively at Clínica RedSalud Mayor Temuco, between 2006 and 2020. Result variables were POM and mortality. Other variables of interest were location and diameter of the tumor, type of surgery, and hospital stay. Descriptive statistics were used. Eleven patients (54.5 %) were treated, with a median age of 56 years. 54.5 % of the tumors were located in the jejunum-ileum. The median tumor diameter, surgical time, and hospital stay were 2 cm, 75 min, and 4 days, respectively. The most frequent type of resection was right hemicolectomy (63.6 %). The MPO was 9.1 % (seroma in one patient). There were no reoperations or operative mortality. With a median follow-up of 18 months, there were no recurrences. Reported results in relation to POM and mortality are adequate in relation to the published evidence.
